Definitions

  • This disclosure relates to the field of accessories for hand and power tools.
  • an optical aid to improve the precision of cuts made by such tools.
  • Woodworking is an ancient and time-honored art, older than written language. Historians have determined that early development of human civilizations was closely related to technological advances in working materials such as wood. While the tools used to craft wood have changed over time, they all serve the same basic purpose: cutting and shaping the material to the desired final form. Modern power tools achieve degrees of safety, precision, and accuracy that hand tools generally cannot.
  • power tools are not without their own limitations. While power tools offer stability and consistent application of force, they also present design challenges. For example, battery-operated tools draw significant power and require heavy batteries which must be recharged frequently. Tools that plug into wall receptacles are confined to locations with access to power and must be engineered so that the power cable is directed away from the path of the cutting surface. Additionally, because the force applied by power tools is very high, power tools present risks of severe injury that hand tools do not. For example, a woodworker with a mallet and chisel or handsaw is very unlikely to sever his hand or fingers, but a circular saw easily poses that risk.
  • barriers made of resilient materials, such as metals and metal alloys, tend to be opaque, obscuring the cutting surface from view. This means that even as the safety features protect the operator, the tool loses some of its precision and accuracy because the operator can no longer directly observe the cutting surface. If, however, the barrier is made of transparent materials, such as plastics, the barrier is generally less rugged, provides less protection, and is susceptible to shattering, splintering, or cracking, which itself poses additional safety risks to the operator.
  • a typical wood router is designed for creating functional or decorative edges to wood boards.
  • the wood router includes a router bit located in the middle of a circular base, the lateral edges of the bit have cutting surfaces, and the motor spins the bit to produce a lateral cutting action. The operator then moves the router along the edge of the work piece to apply the edge.
  • the operator generally need not actually see the router bit itself, he need only know that the router is moving in a straight line along the edge of the board, and this can be accomplished by clamping a straight-edge or guide to the work piece at the proper distance from the edge to be cut.
  • Routers also sometimes have "plunge" modes, where the bit has a ventral cutting surface and the router is placed on a flat surface of the work piece and the bit is lowered into the work piece to bore a hole, such as for accepting a dowel rod.
  • the router is also suitable for tasks such as engraving, the inability to see the router bit prevents the operator from using the router in such free-form applications. Even if the operator could see the bit, the motor housing is located directly above the bit and the shadow of the motor housing obscures the bit, making it difficult for the operator to follow a guide pattern or template precisely.
  • woodworkers often make custom jigs or templates to control the movement of the tool for shaped cuts.
  • These jigs are essentially wooden templates with a channel for the router bit shaped like the desired cut. The jig is clamped to the work piece and the router bit is moved along the channel to produce the desired cut.
  • Making the jig itself takes time and consumes materials and usually is only worth the woodworker's effort if the template will be reused to reproduce the cut on future projects. For example, it would be a waste of time to build an engraving jig for a wood router which carves a person's name into the work piece, as the woodworker is almost certain to never need to carve that specific name again.
  • the jig often requires that the woodworker use other tools because of the above limitations.
  • certain types of engraving simply are not possible using a jig. Where the engraving includes a closed shape, such as the letters "O,” “D,” and "P,” when the channel is cut in the shape of the letter, the center of the closed portion of the shape will no longer be attached to the template and will simply fall out of the jig. The resulting jig would have a wide opening, for example, in the head of the "P" which would permit the router bit to wander off track.
  • Woodworkers thus have little choice but to purchase multiple tools that essentially serve the same function, except that the designs of the tools differ in order to facilitate a particular use.
  • the DremelTM rotary tool is little more than a miniaturized handheld router with no base plate, allowing the operator to see the cutting surface and grip the device for engraving and other free-form work.
  • the absence of a base in a DremelTM tool also reduces its overall stability and causes the bit to more easily jump and skip across the surface of the work piece.
  • Woodworkers thus must own, maintain and sharpen a variety of toolbits, battery packs, and accessories, not all of which are interchangeable and all of which present inherent obstacles to performing certain types of work. Additionally, woodworkers must haul these tools from site to site, requiring additional storage and hassle, and increased risk of loss, theft, or breakage.
  • the optical aid for use with a power tool.
  • the optical aid generally includes one or more reflective surfaces to reflect the cutting surface of the power tool to the operator, improving the precision and accuracy of cuts and allowing the power tool to be used in ways not otherwise feasible because the design of the power tool obstructs the operator's view of the cutting surface when the operator uses the power tool in a natural or comfortable posture or position.
